Dual SIM (Nano-SIM, dual stand-by)
“Dual SIM (Nano-SIM, dual stand-by)” refers to a feature commonly found in smartphones and other mobile devices.
Dual SIM: This means the device has two slots for SIM cards, allowing the user to have two active phone numbers or cellular connections on the same device. This is beneficial for users who want to separate personal and work phone numbers, use different carriers for cost-saving or coverage reasons, or have a dedicated SIM for international travel.
Nano-SIM: This refers to the type of SIM card that the device uses. Nano-SIM cards are the smallest and most commonly used SIM cards in modern smartphones.
Dual stand-by: This indicates that both SIM cards can be active simultaneously, allowing the device to receive calls, messages, and data on both SIM cards at the same time. However, when one SIM card is in use (e.g., making a call), the other SIM card may be temporarily inactive for certain functions.
